P00A2 Bugatti Type 57 Diagnostic Trouble Code
P00A2 Bugatti Type 57 code definition:
P00A2 is a kind of OBD-II Diagnostic P-Powertrain Diagnostic Trouble Code for Bugatti Type 57.
P00A2 Bugatti Type 57 is described as Fuel System Too Rich, which basically means bank 1's oxygen sensor has detected a rich condition of fuel. This means there's not enough oxygen in the exhaust from too much fuel being delivered into the air and gas mixture for combusion. The spark should have a light tan color. If the sensor probe comes with white and chalky parts, this means it has been lagging between switching phases, and should be replaced.
Symptoms
Symptoms of a P00A2 Bugatti Type 57 diagnostic trouble code may include:
- Faulty or damaged wiring
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
- Poor fuel economy
- If the DPF is not cleared the ECU will revert to the "Limp Home Mode" until the situation is corrected
|
Possible Causes :
- A large air leak at or near the number one oxygen sensor would also cause a lean mixture.
- Faulty IMRC actuator relay (if equipped)
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.

Common Misdiagnoses
- Exhaust Gas Recirculation System Valve 1 Problem
- BBV Sensor Circuit Low Voltage Problem
- Transmission Engaged At High Throttle Angle Problem
- Cruise Inhibit Control Circuit Problem
- TFP Valve Position Switch-Drive Without Drive Ratio Problem
Repair Processes :
Look for rubbing, scraping, bare wires, worn spots or melted plastic connectors. Pull the connectors apart and carefully look at the terminals (the metal parts) inside the connectors.
Look for missing ground strap or a rusty ground where the fuel tank is grounded to the frame. Check for damage to the wiring harness connector.
